Fusion made their Signature Series marine amplifiers to perform in the most challenging conditions. They're designed to resist moisture, while delivering the power your music needs to be heard over the wind and waves. This Signature Series SG-DA41400 4-channel amp delivers 150 watts RMS to each of your Zone 1 and Zone 2 speakers, so you'll get plenty of sound, wherever you're standing. You can also use the amp in 3-channel mode, powering one set of speakers with the front channels, and sending 440 watts to a sub with the rear channels bridged. The SG-DA41400's rugged aluminum alloy chassis acts as a heat sink, dissipating heat and increasing efficiency.

A great-looking amp

The stylish stainless steel front panel resists corrosion, plus it adds an undeniable touch of style to your installation. You'll find separate high- and low-pass crossovers for Zone 1 and Zone 2, so you can adjust for each area. A bass boost on channels 3 and 4 allow you to punch up the bass if you're using these channels to power a subwoofer. 

Built to last

A conformal-coated circuit board and water-resistant design ensure that this marine-rated amp will stand up to conditions that turn lesser electronics into ballast. As part of Fusion's True Marine line, the SG-DA41400 is backed by a 3-year warranty.
